I always hear about Stage I, Stage II, etc... What makes it Stage I or Stage 5?

I think it has to do with upgrading the components of the turbo kit. For example if you were to upgrade the SRT-4 turbo kit to stage 2 this is what you would add to it. http://www.mopar.com/street/tech.htm

usually its upgrades for more power.like bigger injectors,reprogram ecu, bigger turbo and stuff like that lie the mopar srt-4 stuff.some cheaper kits offer stage 1 as no intercooler and minor fuel mods(like adjustable fpr) and stage 2 as intercooler and 3 as real fuel management.etc.
